Title: Improvements relating to ion-exchange apparatus
Inventor: MAZIJK ANTOON PIETER VAN
IPC: B01J49/00
Filed: 1962-11-16
Abstract: 1,010,923. Ion-exchange. PERMUTIT COMPANY Ltd. Nov. 6, 1963 [Nov. 16, 1962], No. 43458/62. Heading B1J. An ion-exchange apparatus comprises a cylindrical vessel 1 housing a charge of baseexchange resin, an inlet 2 leading to an internal tube 3 through which raw water from a pipe 4 is introduced to be softened by upward flow through the resin, and an outlet 5 leading to a pipe 6 for the softened water. When the resin is to be regenerated a constant volume of brine is introduced through the pipe 6 to flow downwardly through the resin, and the spent brine regenerant flows up the tube 3 to the pipe 4 by the use of the valve chamber 13. This chamber has upper and lower valve seats 47 and 48 concentric with the ends of the cylinder, and it contains a ball 49 that is of specific gravity slightly less than that of brine. Below the lower seat 48 there is a port 50 to which the pipe is connected, and above the upper seat 47 there is a cylindrical space 51 in the side of which there is a port 52 connected to the pipe 15 and at the end of which there is a bleed opening 53. When suction is applied to the pipe 18 a small amount of liquid is drawn through the opening 53, but the major flow is through the pipe 15 and port 52. Since the liquid above the opening 53 may well not be a saturated solution, in contrast to that at the bottom of the container which will always be a saturated solution as long as there is solid salt in the container, it is important that the bleed opening 53 should be small. A strainer 54 is mounted above the opening 53 to prevent solid particles fouling it, and the strainer is in turn placed immediately below the outlet of the pipe 27. In operation, regeneration is initiated by opening the solenoid valve 38, which may be done under automatic control. Brine is then slowly drawn up to the top of the chamber 13 and flows downwards through it. The ball 49 floats in the brine in the chamber but is readily forced off the upper seat 47 to allow the brine to flow. The level of brine falls from the level X-X until it reaches the opening 53. Air is then drawn into the chamber 13, the level of brine falls in it, and the ball 49 becomes seated on the lower seat 48. No more brine flows from the container 10, but suction is maintained while the base-exchange resin is washed with water flowing through the inductor 14. Specification 1,010,924 is referred to.

In a method of fluorescent X-ray analysis the count rate Iα, I#, Iγ, 1#, from the specimen is measured using two pairs of balanced filters with absorption edges at (E 1  +α), (E 1  -#); (E 2  +γ) (E 2  -#) respectively bracketing the characteristic energies E 1 , E 2  of a wanted element and the quantity of the wanted element is determined from a calibration curve of quantity against. The method eliminates the masking effect of one element on the other due to the absorption of the others characteristic X-rays. If the characteristic wavelengths of the elements are close, a single filter may serve for one of each pair. Anhydrite and magnesite ores may be tested for Cu in the presence of Fe using Ni/Co and Mn/Cr or Mn/Co filter combinations excitation being provided by gamma rays from Cd 109.

Title: Improvements in or relating to telecine equipment
Inventor: DEVESON JOHN HARWOOD
IPC: H04N5/253
Filed: 1968-09-18
Abstract: 1,270,264. Television. MARCONI CO. Ltd. 14 July, 1969 [18 Sept., 1968], No. 44273/68. Heading H4F. When employing a television camera to scan cine-film to produce video signals, it is possible to compensate for variations in the film exposure by detecting the peak video signal, comparing it with a desired value e.g. that for white and subsequently reducing the peak video signal to the desired value e.g. by varying the intensity of a light source illuminating the film, or by varying the gain of the camera or video signal amplifier. Such systems which detect and control the peak signal value continuously must however have a long response time to avoid demodulating the video signal. In the present invention, only the peak signal amplitude is determined during a first predetermined number of television fields (at least one) and any departure from the desired value is corrected for only during a subsequent predetermined number of fields (at least one) thereby permitting a rapid response without signal demodulation. In the embodiment shown, the four outputs of a colour camera viewing the film are fed to a gate 2 with an output and a peak detector 3 equal at any instant to the largest of the input signals. The output of the peak detector is fed via a switch 5 to an integrator 6 which serves to compare the peak signal with a reference white value at 10 and produces a corresponding output at 7 controlling a servo motor determining the rotational position of a variable density filter placed between light source and the film. With the detector 3 initially set to zero and switches 5, 8 open, a signal from the gate 2 is applied to the detector for two field periods. The switch 5 is then shut during the next field blanking period so that current flows through the resistive inputs of the integrator 6 to a differential amplifier 9 and a capacitor C1 is charged to an amount depending on the measured and reference peak signals. Two fields are then allowed for the servo to operate and during the next field blanking period, the switch 8 is closed to reset the detector 3 to zero and the cycle is repeated. The inputs to amplifier 9 include a diode D1 whereby response to too high peak levels (over-exposure) is far more rapid than that for too low peak levels, (under exposure). In a second embodiment, in the drawing accompanying the complete Specification (not shown), the luminance output of a colour camera is blanked in a blanking mixer and inverted. The black level is then measured by a peak detector and switches 8, 5 and integrator 6 fed this time with a black reference signal, produce a correcting signal every four fields as before. The correcting signal is used to control the clipping level of a clipper fed with output from the blanking mixer. As an alternative, the output of integrater 6 may be used to vary a video amplifier gain, but this is said to produce some degradation in the signal.

Title: A process for preparing nuclear fuel elements of dispersed-in-graphite type
IPC: G21C3/64
Filed: 1964-11-03
Abstract: A nuclear fuel element in which a uranium compound is homogeneously dispersed as minute particles of less than 5 microns diameter in a carbon matrix is prepared by pouring a mixture of resin-forming materials to which a uranyl salt has been added into a mould and solidifying the mixture by condensation polymerization in the presence of a small amount of hydrochloric acid as catalyst to give a high polymer resin in which uranium exists in a chelated state, the solidified resin being cured in air and then carbonized in an inert atmosphere, the temperature being raised gradually until the resin becomes an impermeable carbon body, and finally the carbonized body being heated in a hydrogen atmosphere until the carbon is graphitized in the degree of 12 to 16%.  In a preferred embodiment, 20 grams of uranyl nitrate hexahydrate were dissolved in 200 ml. of furfural, two mols of which were mixed with one mol of phenol and small amount of concentrated hydrochloric acid added.  The mixture was poured into a smooth-surfaced mould of 10 mm. diameter and 100 mgm. length, and was exposed to the air at 80 DEG  C. for about 36 hours during which time condensation polymerization proceeded.  After the mixture had solidified and hardened, the formed resin mass was removed from the mould and kept in the air at 80 DEG  C. for about two weeks and then at 120 DEG  C. for about one week to obtain a black resin mass in which the uranyl radical was evenly distributed. The uranyl - containing resin was heated in an argon atmosphere in an ohmic resistance furnace, the temperature being raised by 100 DEG  C./hour up to 500 DEG  C. and then by 200 DEG  C./hour up to 1200 DEG  C. at which temperature it was kept for 1 hour before being cooled slowly to room temperature.  By this treatment the resin was carbonized. The resultant product was heated in a hydrogen atmosphere for 1 hour at 2550 DEG  C. and was then slowly cooled to room temperature. X-ray diffraction tests showed the graphitization degree was 12 to 16% and peaks of oxides of uranium were not observed. Radioautography indicated that the uranium was distributed homogeneously throughout the fuel element.
